| Research Abstract |
One of αィイD21aィエD2-adrenoceptor subtypes ,αィイD21aィエD2-adrenoceptor is implicated in the pathophysiology of benign prostatic hypertrophy (BPH). We examined polymorphism of the human ala-AR gene (Arg492 to Cys) in 222 BPH patients. There was no significant association of αィイD21aィエD2-adrenoceptor polymorphism with clinical (onset and degree of symptoms, size of BPH and response to αィイD21aィエD2-adrenoceptor blocker) and laboratory data (cholesterol and other lipid data, prostatic specific antigen, testosterone level) of the patient with BPH ; however, the allele frequency in Japan was markedly different from US populations. The results did support the idea that BPH is associated with alterations in αィイD21aィエD2-adrenoceptor gene.
